I bought a 020 week before last. During the seasoning smoke the wife came in so I was showing her how to set the cook temp. It was running at 200, but an hour or so after that it went to 275. The next day I cooked some ribs @ 225, after 4 hours I set the temp to 140 to hold till supper. I went back in a little while and the temp had run to 255. Now I'm sure I have a problem. I contacted CS and talked to Tony, told him my problem, he asked a few questions, and said he'd call me back in a few. When he called back he told me he had done some checks and was pretty sure I had a bad controller. He offered to trade the whole unit or to send me a controller and let me change it out myself. I opted for the latter. In a couple of days I had a new controller, no charge plus a return shipment label. I installed the new controller and my CS is working great. It's refreshing to deal with folks that care about their customers.
Thank you to Tony and the CS staff.
